OIL-BURNER.

Specification of Letters Patent.

Patented J an. 21, 1919.

Application iled September 20, 19,18. Serial N o. 254,946.

To all whom t may concern:

Be it known that I, JOHN F. REILLY, a

subject of the King .of Great Britain, and a resident of CentralAguirre, in the county of Guayama, Porto Rico, have invented'a new andImproved Oil-Burner, of whichthe following is a full, clear, and exactdescription.

This invention relates to Oil burners and particularly to burners whichmay use crude oil as well as refined oil, and has for an object theprovision lof an improved construction wherein the oil is sprayed w1thsteam in order t0 secure high efiiciency.

`Anotherobject 'in view is to provlde a bln-'ner having 1a steam and oilinlet wlth a mixing chamber and spraying chamber adjacent its dischargemouth so that the oily will be heated, sprayed and mixed with steamsubstantially simultaneously.

A still further object of the invention is to provide a burner which ismade in a minimum number of ,parts and which acts to produce a properspray without utilizing any Inovlng parts.

In the accompanying drawing:

Figure 1 is a longitudinal vertical section through a burner disclosingan embodiment of the invention.

Fig. 2 is an end View of the burner shown in Fig. 1. i

Fig. 3 is a 'top plan view of the burner shown in Fig. 1.

Fig. 4 is a rear end view of the structure shown in Fig. 1.

Fig. 5 is a perspective view of the burner with a front section remoyed.f

Flg. 6 is a perspective view of the front section of the burner shown inFig. 5.

Referring to the accompanying drawing by numerals, l and 2 indicate thefeed pipes, pipe 1 supplying steam under pressure, while pipe 2 suppliesthe fuel oil, which may be crude oil or refined oil as desired. Thesepipes feed into what may be termed chambers 3 and 4 of the casing 5,which casing has substantially semi-circular openings 6 and 7 openinginto the notch 8, which notch,

is filled by a removable front section 9 when the burner is in use asshown in Fig. -1. This section fits snugly and is held in place bysuitable screws 10 and 11. Section 9 covers the opening 7 except for thepart which registers with the passageway 12, said passage` way leadingdown to a mixing chamber 13. The opening 6 is partially closed by thesection 9 with the exception of a small compara-V tively iiat passageway14 which is restricted at 15 so as to provide velocity for the steam asit enters the mixing chamber 13. The oil is fed through the assageway l2at comparatively slow speed) while the steam moves at high speed so thatthe velocity of the mixture will be considerable and the steam and fuelwill quickly and intimately mix into a fine spray, which spray isignited usually some'distance from the burner. By reason of the mixingchamber 13 and the way the passageways 12 and 14 are provided thedischarge mouth or opening 15 directs a combustible mixture to acomparatively great distance or short distance according to the force ofthe steam. In order to secure the maximum result the mouth 15 isprovided with diver ing walls 16 and 17 .whereby the discharge 1ssubstantially confined between the dotted lines shown in Fig. 3, saiddischarge being in aflat horizontal fuel oil and the steam are suppliedin any desired volume and any desired proportion, the proportion being,of course, adjusted to produce the most eicient action when mixed withthe air supplied by any desired air supplying structure.

e burner may be used in steam boilers or in heating devicesnf'anykindwhere there is a space for the proper use of the sprayed fuel providedby the burner. In connection with the restricted portion 15 it ,will be'observed that the same is restricted vertically,

sheet. ,The

portion is gradually widened from the inner to the outer end of thepassageway 14 so as to provide a thin spray or sheet of steam at'comparatively high speed in order to break up the fuel 011 entering thechamber 13 through passageway 12.

What I claim is:

1. -A burner comprising a casing having a pair of spaced chambers, and anotch in the front end merging into the lower part of the .upper chamberand the upper part of the y lower chamber, the bottom of the notch beingflat, a removable section fitting into said notch, said removablesection having a discharge opening merging into the mixing chamber,saidA discharge opening and mixing chamber having diverging walls, theupper face of the discharge opening being parallel .with the lower faceof said notch, whereby the discharge through the discharge opening willbe in a thin horizontal sheet, a

passageway extending from one of said Chambers into said mixing chamberin line with the lower part thereof, and a second passageway extendingat an appreciable angle to the mixing chamber and merging into themixing chamber and into one of said first mentioned chambers.

2. A burner comprising a casing having an upper and lower chamber, saidupper chamber being adapted to receive a liquid fuel and the lowerchamber adapted to receive steam under pressure, a iat horizontal-Leeaen passageway extending from said lower chamber, said passagewaybeing restricted vertically toward the outer end thereof, a diagonalfuel passageway extending .from said fuel chamber to a pointintersecting the rst mentioned passageway, and a mixing chamber at thejuncture of said passageways merging into a discharge opening, saiddischarge opening being in the form of a horizontal slot whereby therewill be produced a sheet of mixed li uid fuel and steam. l
